Hello there!
In this case, according to the information in this problem, and considering these two bases are strong, it is necessary for us to calculate the total moles of OH ions as shown below:
Now, the as the solutions are additive, the total volume is then 0.100 L and the concentration:
And therefore, the pH is:
Regards!
Answer:
<h2>The answer is 0.95 L</h2>
Explanation:
In order to find the volume when the pressure is changed to 5.30 atm we use Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final volume
From the question
P1 = 2.82 atm
V1 = 1.79 L
P2 = 5.30 atm
So we have
We have the final answer as
<h3>0.95 L</h3>
Hope this helps you
Answer:
See explanation
Explanation:
Freezing point and melting point increases slightly at higher altitude
The boiling point decreases at higher altitudes.
Air pressure decreases with altitude As a result of this, atmospheric pressure decreases and water must now boil at a lower temperature. In order to compensate for this lower boiling point of water, food must take a longer time to cook. The lowering of air pressure actually means that the air becomes thinner at higher altitudes.
Pressure cookers cook food at high pressure thereby reducing the cooking time significantly. This helps to retain 50% of the nutrients in the food, lower the kitchen temperature and lower the energy cost required to cook food.
17) 2 - temperature is a measurement
18) 4 - the unit for energy
19) 1 - all others are measurement and stuff
20) 2
21) 4
29) 1 and 3 - energy is being added
